Setup
Before initial use, inspect the wrench for any signs of damage or wear. Ensure the adjustment nut moves freely and the jaws are clean. No complex assembly is required for this tool.
Operating Instructions
To effectively use the RIDGID pipe wrench:
- Adjust Jaw Opening: Rotate the nonstick adjustment nut to open or close the jaws to fit the pipe diameter. Ensure the jaws are slightly larger than the pipe before positioning.
- Position Wrench: Place the wrench jaws around the pipe, ensuring a secure fit. The full-floating forged hook jaw should engage firmly with the pipe surface.
- Apply Pressure: Apply firm, steady pressure to the handle in the desired direction of rotation (tightening or loosening). The I-beam handle provides leverage for effective torque.
- Ratchet Action: For continuous turning, slightly release pressure and reposition the wrench for the next grip, utilizing the ratcheting action of the jaws.

Troubleshooting
Most issues with the pipe wrench can be resolved with simple checks:
- Wrench Slipping: Ensure the jaws are properly adjusted to the pipe size. Check for excessive wear on the jaw teeth; if worn, replace the hook and heel jaws.
- Difficulty Adjusting: Clean any accumulated grime from the adjustment screw and shank. Apply a lubricant to ensure smooth movement.
